• Sublimation

Check the TWO things that happen to particles when heat is added.

• They get closer together.

• They spread farther apart.

• They move faster.

• They move slower.

What causes a substance to change phases?

• when heat is added or taken away

• only when particles move faster

• when particles stop moving

• when seasons change

Melting is ...

• liquid to solid
• solid to liquid
• solid to gas

Evaporation is ...

• liquid to gas
• gas to solid
• gas to liquid
• solid to liquid

What is sublimation?

• phase change between solid and liquid
• pahse change from gas to solid
• phase change from solid to gas
• phase change from solid to solid
